SPECIFICATION forming part of Letters Patent No. 399,079, dated March 5, 1889.

Application filed August 27, 1887. Serial No. 247,997. (No model.)

the pairs of vertical copper pipes, secured to the base-pipe in the manner hereinafter deand State of New -l scribed; and D, the cap for the vertical pipes, said cap having a perforated or open top and f beingof suitable configuration to suitabl f ornament the radiator. Any suitable number of base-pipes B may be employed, according' to the size ot' the radiator and its requireof the horizontal base-pipe and the vertical pipes extending upward therefrom, whereby all screw-joints are dispensed with and the g pipes adapted to contract and expand to a maximum degree withoutdanger of leakage or damage to them, another advantage accomplished being that the horizontal and vertical pipes being of thin copper the radiator may be quickly heated, the rapid expansion not having any injurious effect. The radiator constructed according to the invention, while thoroughly effective in operation and successfully fuliilling its requirements, is simy ple in its arrangements, light, and comparatively inexpensive.

The invention will be more f ully understood from the detailed description hereinafter presented, reference being had to the accompanylug drawings, in which- Figure l is a side elevation, partly in section, of a radiator constructed according to the invention, the cap and base being in section, and a portion of the copper base-pipe and vertical pipes being in section on the broken line Y 'Y of Fig. 2, which is a horizontal transverse section of the radiator on the broken line X X of Fig. l. Fig. 3 is a vertical transverse section through the horizontal jecting lip on the upper edge of the flange I base-pipe and one pair of the perpendicular pipes secured thereto, the section being presented to illustrate the manner of securing g the perpendicular to the horizontal pipes; and l In the accompanying drawings, A indicates l desired to secure the pipe G in position, and

ihc base or stand of the radiator, which will metal, having legs which elevate it from the i be removed for the floor; B, the horizontal copper base-pipe; C, l ter finish to the apparatus.

ments.

In the accompanying drawings I have illustrated a radiator having three of the basepipes B, the steam being admitted at E, and after circulating through said. pipes and through the vertical pipes is allowed to escape at F. Each pair of pipes O consists of an inner pipe, G, and an outer pipe, H, the inner pipe being open top and bottom and being brazed to the upper edge of the outer pipe, as illustrated in Figs. l and 3, while the lower end of the inner pipe, as well as the lower end of the outer pipe, is brazed to the pipe B. The pipe B along its upper andlower surface is provided with the vertical flanges I J, respectively, said flanges being circular in outline, and the flange .I being' centrally below the flange I and of smaller diameter. The lower ends of the inner pipes, G, lit within and are brazed to the flanges J, while the lower ends of the outer pipes, H, lit within and are brazed to the flanges l.

In Fig. 4 I illustrate in an enlarged view the method of brazing the lower ends of the pipes G H to the flanges I J, and in this figure it will be observed that the upper edge of the flange I is deflected outward, forming a lip,

which receives the b azing metal,whereby the pipe His secured and vretained in position. After the pipe H has been secured the prowhich lip, after the pipe has been secured,will

purpose of affording a bet- The upper edge The flange J IOO of the outer pipe, H, is pressed against and impinges the upper edge of the inner pipe, G, whereby the brazing metal, when introduced, forms a close union between the pipes at their upper end and prevents the escape of steam.

In the operation of the invention the steam passes through the pipe B and through the spaces formed between the pipes G H, thence escaping through the valve F, the air in the meantime being permitted to enter the lower end of the pipes G and escaping through the cap D. The base-pipe B and the pipes G H are of thin copper, and as a consequence when the steam is admitted to the radiator they bccome quickly heated and give forth the heat into the apartment. The manner of securing the pipes G H together at their Lipper ends and to the base-pipe B at their lower ends is such that thin copper pipes may be used without danger of the sudden expansion and contraction to which they are subjected when in use, causing the joints to separate or become in1- paired. The flanges I J, securing the lower ends of the pipes G H, are adapted to permit a large` amount of expansion and contraction in said pipes and in the pipe B without danger of leakage, and the entire absence of screwthreads renders the radiator particularly safe and durable. All of the pipes being of thin copper, the radiator will be very light and may be easily handled.

It will be observed that the pipes B are circular in cross-section and are independent of the cast base A. I secure certain advantages by constructing the radiator as above described and employing thin copper pipes in this construction which are not attained in the radiators heretofore known. For example, in iny structure the upperl edge of the pipe H is folded in against and brazed to the upper edge of the inner pipe, G, and this forms at the point in the outer pipe where the metal is bent inward a surface Where expansion and contraction can occur without affecting the brazed joint between the pipes. This result is secured owing to the fact thatthin copper is employed, and it is a desirable and an iinportant result. Another important result I gain is that by the use of the thin copper pipes B as base-pipes I secure in the circular side walls of said pipes an expansion and contraetion surface which may be affected by heat and lcold without danger of loosening the joints formed at the union of the pipes G H with said base-pipes. These results above mentioned I am enabled to secure by the use of copper pipes, and, in addition, the radiator constructed as described is light, durable, and inexpensive. Iron radiators, though employing inner and outer vertical pipes, are incapable of accomplishing the results which I attain by the use of copper pipes arranged in the manner above described.

What I claim as my invention, and desire to secure by Letters Patent, is

In a radiator, the base A and the base-pipe B, circular in cross-section and having the flanges I J, combined with the pipes G H, brazed to t-he flanges I J respectively, the upper edge of the outer pipe, H, being closed against and brazed to the upper edge of the inner pipe, G, and all of said pipes being constructcd from thin sheet-copper, substantially as and for the purposes set forth.
